The one i have does not have all the wires that i have in my connector on body harness connector since it's a 2009.5 build.

For some reason I can't get the ecu to turn on in my ute, so upon checking the plug found that it was broken on the leverage arm thus not making solid contact. Moved all the pins across from 1 connector to the other and still nothing.

I can program it on the bench fine so i know it's good.

If someone has a active tis2web sub and can grab for me it would be appreciated. Car vin = 6G1EP4EY3AL420001

Sorry, I can pull it up in an IVR, but I can't get to it in Service Information.. Below is your rpo codes in case that makes you feel any better.. lol..

L76 does show up as an engine in a 2009 Silverado, not 2010 though.. Below is the power ground schematic, that has everything you should need to get the ECM to wake up and talk..Circuit 18(D blue) isn't needed to talk ,but it gets ignition power from the key and signal is passed thru the BCM..Pretty sure Circuit 47(Pink/blk) isn't needed to talk either
